TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented nee.1e,1a1c.

To all 07mm it may concern Be it known that I, CORNELIUS B. COR- coRAN, a citizen of the United States, residing in the borough of Bronx, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a Specification.

This invention relates to improvements in paper alining devices for typewriting machines, such for instance as shown in the patent to Harry dated July 5, 1910. j

Heretofore when a written sheet was inserted a second time, it was necessary to adjust the sheet at its top and side edge, to bring the first written line to the printing position, after which the platen had to be turned until the first blank line appeared.

Anobject of my invention is to avoid such manipulation of the paper, and to this end I arrange to guide the work sheet by means of both its side edges, and initially adjust the paper directly at the line to be written upon. The aliner is adaptable to sheets of various widths. The top gage may, however, be retained for use with certain kinds of work, in connection with either one or both of the side gages.

The alining table 'may Ycomprise plates yoverlapped to form a continuous support for the work-sheet, andeach having along its outer edge a gage for the side edge of ,x the work-sheet, said plates being separately adjustable in the direction of the platen axis to adjust the position of the side edges of the work-sheetsand, also to accommodate work-sheets of different widths. The upper and lower edges of the plates may be formed with telescoping beads, a set screw being provided to lock the plates together in adjusted position. The alining table is supported by brackets, one adj ustably connected to veach plate, permitting adjustment of the table toward and from ythe platen, the brackets slidably mounted on a rod parallel with the platen, and a latch pivote'd to one'- bracket'to engage notches in the said rod to hold the table in adjusted position.

Other objects and advantages'willhere'ein after appear. A g j In the accompanying drawings, Flgure 1 is a top.v plan view ofthe aliner mounted 'upon a platen frame. "Fig. 2' is a cross sec# S. McCormack, No. 963,629,

The usual typewriter platen frame 1 comprises papery table 2 and ends 3, 4, which carry journals for the axle 5 of platen 6. Between the ends 3, 4, extends a shaft 7 and mounted upon this shaft by means of brackets 8 and 9 are two telescoping plates 10, 11, which may be extended or closed to make their opposite side gages 12 fit sheets of various widths.

Since the side gages 12 are of considerable length, it is practicable to use these gages alone for gaging or justifying the work sheet, without the aid of the top gage 14, in many cases; the side gages being relatively adjusted so that the sheet will just fit between them. By means of these side gages, which are at right angles tothe platen, the horizontal lines of printing or writing on the work sheet are brought parallel with the platen. Hence it is practicable to introduce the sheet into the machine and vplace `it between the side gages and then at once by advancing or retracting the sheet to bring the first blank line directly to the printing point, without a preparatory gaging of the top edge of the sheet to theA One alining plate 11 extends beneath the other plate 10,i `to telescopev with it. This gives a continuous paper rest or table between the two side gages 12, upon which the operator may press his fingers whilel locating a sheet.v The alining plates 10 and 11 are held in proper relation to each other by telescoping. beads 16 and 17 on the plates 10 and 11 respectivelyfsaid beads being pro-v vided on both the upper and lower edges of the plates; the beads 16) forming guideways` for the beads 17 to slide in. Each of the alining plates 10, 11, is supported by only one bracket 8 or 9 at its outer end, but the telescoping beads 16, 17 coperate to serve as supports for the inner ends of the plates, and prevent sagging.

A dog 18 pivoted at 19 to the bracket 8 is adapted to enter any one of a series of notches 20 in shaft 7 and prevents lateral disspring 2l, and may be withdrawn by means placement of the alining plates. This dog 18 is normally held in locking position by a of a linger piece 22 whenever it is desired. t0 move the left alining plate. The right alining plate 11 moves together with the left alining plate 10, being locked thereto by thumbscrew 15, but when this screw is loosened, each plate may be adjusted relatively to the other.

The brackets 8, 9, are mounted upon the rod.7 by means of yokes 23. A spring 24 seatedl in each yoke, presses a key into a groove 25 vin the rod, whereby the alining table 10, 11 is held firmly, but maybe swung around the rod or shaft if desired, the brackets being journaled on the rod.

Variations may be resorted to within the scope ofthe invention, and portions of the .improvements may be used without others.
